Authorities seized nearly 2 pounds of methamphetamine, more than 2 ounces of heroin, more than $6,000 in cash and one car in several drug investigations this month in Polk County.

The drugs -- with an estimated street value of more than $41,000 -- were being distributed throughout non-incorporated Polk County and also in West Salem, Dallas, Monmouth, Independence, Falls City and Grand Ronde, Polk County sheriff's officials said.

"The cases ... are very significant for our county, because these cases reached just about every corner of Polk County, including every city," Detective Sgt. Mark Garton said in a statement.

Investigators arrested five people, including William Daniels, 54, of Lincoln City, and Christopher Perez, 33, of Falls City, both on allegations of unlawful delivery and possession of methamphetamine. More arrests are expected, sheriff's officials said.

The investigations were conducted by the Polk County Inter-Agency Narcotics Team.
